Abstract
The efficiency of water use to produce biomass is a key trait in designing sustainable bioenergy-devoted systems. We characterized variations in the carbon isotope composition (C-13) of leaves, current year wood and holocellulose (as proxies for water use efficiency, WUE) among six poplar genotypes in a short-rotation plantation. Values of C-13(wood) and C-13(holocellulose) were tightly and positively correlated, but the offset varied significantly among genotypes (0.79-1.01). Leaf phenology was strongly correlated with C-13, and genotypes with a longer growing season showed a higher WUE. In contrast, traits related to growth and carbon uptake were poorly linked to C-13. Trees growing on former pasture with higher N-availability displayed higher C-13 as compared with trees growing on former cropland. The positive relationships between C-13(leaf) and leaf N suggested that spatial variations in WUE over the plantation were mainly driven by an N-related effect on photosynthetic capacities. The very coherent genotype ranking obtained with C-13 in the different tree compartments has some practical outreach. Because WUE remains largely uncoupled from growth in poplar plantations, there is potential to identify genotypes with satisfactory growth and higher WUE. The carbon isotope composition ((13) C) is often used as a proxy for water use efficiency (WUE). For six poplar (Populus) genotypes in a short-rotation (bio-energy) plantation the values of C-13(wood) and C-13(holocellulose) were tightly and positively correlated, but the offset varied significantly among genotypes. The positive relationships between (13) C-leaf and leaf N suggested that spatial variations in WUE over the plantation were mainly driven by an N-related effect on photosynthetic capacities. As WUE remained largely uncoupled from growth, there is potential to identify poplar genotypes with satisfactory growth and higher WUE.
